Filed: 1975-05-22
Abstract: 1481638 Blow-moulding E I VALYI 22 May 1975 [14 June 1974] 22232/75 Heading B5A A hollow article is formed by blow moulding a parison 16 and transferring the blown parison 29 on a core 58 to a temperature adjusting retaining mould 24 where the core is removed and the temperature of the blown parison is adjusted before it is removed from the retaining mould. The parison may be of a variety of plastics and made by extrusion, injection moulding, dipping, or thermo-forming. In Fig. 4A a parison 16 is injection moulded about a blow core 15 having a neck ring 21 and lowered to the dotted line position on the core 15 to enable the blow mould 23 to be brought to the left and aligned with it. The core 15 is raised into the blow mould and the parison is inflated to form an article 29. The core 15 is withdrawn, the mould 23 moved to the right, and a transfer core 58 is raised to engage the article 29 (as shown). The article is removed by the descent of the core 58 to the dotted line position, the mould 23 and a retaining mould 24 connected thereto are moved to the right, and the core 58 is raised to position the article in the retaining mould 24 and then lowered. The article is held against the walls of the blow mould and the retaining mould by vacuum applied through lines 23<SP>11</SP> and 24<SP>11</SP>. The article 29 is removed from the retaining mould 24 after cooling to the desired temperature by expandable transfer fingers 35 mounted on a turntable. Instead of the mould 23 and 24 being reciprocated in unison four conditioning moulds 24 may be mounted on a turntable 37, Fig. 9, to give a longer conditioning time. A parison 57 may be injection moulded about a liner 51 supplied to the injection mould 10 by a rotary turntable (Fig. 6, not shown) or by a carrier assembly 52, Fig. 7A, mounted to move in unison with the moulds 23 and 24 and drop the liner into the mould 10.

Title: Improvements in or relating to heat treating apparatus
Inventor: CUBBON ROBERT CLIFFORD
IPC: C21D9/56
Filed: 1962-06-08
Abstract: In a process and apparatus for the continuous heat-treatment of metal strip the latter is first heated by passage through a liquid heat transfer medium, is then further heated by radiation in a non-oxidizing atmosphere, and is then quenched by passage through a liquid heat transfer medium at a lower temperature than the first medium.  The same liquid medium may be used both to heat and to quench the strip and is in that case circulated in counter-flow to the strip.  While the strip is being subjected to radiation it may be additionally heated by the passage of electric current.  As illustrated, strip 11 follows a path defined by rolls 12, 15, 19, 21 and 26, in the course of which it passes first through limbs 14 and 16 of a U-shaped channel containing a liquid heat-transfer medium, is then further heated by banks of radiant heaters 18, and is then quenched by passage through a second U-shaped channel 20, 22. Additional heat may be supplied by the input of electric current through line 30 and roll 19, rolls 15 and 21 being earthed.  The liquid, which may be lead-bismuth alloy, is circulated by pump 42 through limbs 22, 20, 16 and 14 in counterflow to the strip, returning through heat exchanger 46; it is maintained at appropriate treatment temperatures by heaters 49. <PICT:0980353/C6-C7/1>

Title: Spray device and method of dispensing liquids
IPC: B05B9/08
Filed: 1960-06-27
Abstract: 920,364. Spray-producers. SUNBEAM CORPORATION. June 27, 1960 [Aug. 13 1959], No. 22512/60. Class 69 (3). A resilient container 11 of rubberlike material has a closure 20 removably attached in pressuretight manner, and liquid to be sprayed is fed to the container under pressure via a one-way valve 30 and passageway 26, whereby the container is expanded, and energy for dispensing the liquid is stored in the container walls. When a valve 42 is opened by a trigger 44 liquid is forced through a tube 40, passage 41 and hose 49 to a spray nozzle at substantially constant pressure. The closure includes a handle 25, a hose connector 28 for the liquid feed supply to the container, and a flange 20b which is forced on to an integral flange 11a of the container by an annular rotatable adapter 17. The latter has opposed lateral flanges 17d which, when the adapter is twisted on the flange 11a, engage opposed ears 20c of gradually increasing thickness on the flange 20b. Insecticide &c. is initially placed in the container after removing the closure, and water under pressure is then supplied to the container when the closure has been applied. An indication of the amount of liquid held in the container is provided by a lever 32 pivoted at 31 which is urged outwardly by the container wall against the action of a spring 35, and indicia 38 on the lever associate with an index on the closure. The container may be surrounded by a rigid enclosure to limit its maximum filling.

Title: Pressure arm particularly for devices for drawing textile fibres
IPC: D01H5/56
Filed: 1958-07-15
Abstract: 859,924. Drafting apparatus. SOC. ALSACIENNE DE CONSTRUCTIONS MECANIQUES. July 15 1958 [July 28,1957], No.22654/58. Class 120(2). So that the top rollers can be positioned where desired, the arm 1 carrying them has a slideway along which roller-supporting members 14 may be moved and has positioning means co-operating with complimentary means on the members, the latter having resilient means serving both to lock the members in desired positions, and also to press the rollers against the lower rollers or other members with which they co-operate in the working position. The slideway is provided by forming the arm as a channel-member having teeth 17, 19 co-operating with teeth 16, 18 on the members 14 to form the positioning-means. Each member 14 comprises outer and inner parts 14, 15 Fig. 2: the latter acts as a piston terminating in a resilient clamp 15c holding the roller spindle, and has lugs 15b Fig. 2, which protrude through the walls of the outer part 14 into grooves 1a in the walls of the arm. The outer part 14 carries a block having the teeth 16. When it is desired to adjust the position of a roller, the block is pulled downwardly against the action of a spring 23 between the two parts of the member 14 to free the teeth and permit the member to be moved: it is then released so that the spring forces down the piston 15 until the lugs 15b engage the lower faces of the grooves 1a whereupon the spring forces the outer part upwardly for the teeth 16, 17 to engage. When the arm is lowered the rollers engage with their co-operating rollers &c. and the piston is forced upwardly to separate the lugs 15b from the bottom of the grooves 1a and allow the part 14 to descend whereby the teeth 16, 17 are disengaged the teeth 18, 19 however remaining in contact. To allow for a fine adjustment of the members 14, the teeth 19 are provided only on one side of the arm, and the pistons are offset from the centre of the members 14 by one quarter of the pitch of the teeth so that according to which way round the member 14 is inserted in the slideway the position of the roller may be adjusted by half the pitch of a tooth. The arm is mounted on a support 25, adjustment being allowed by teeth 28, 29 engaging the racks: the arm can be locked by rotating a screw passing through an enlarged nut 27 held with its sides in the grooves 1a to force the support against the top of the arm.

Title: Control of electromechanical power transmission systems
IPC: G05D13/00
Filed: 1945-09-05
Abstract: 629,526. Transmitting mechanical power. NEWTON, F. Sept. 5, 1945, Nos. 22874 and 31997. [Class 38 (iv)] In a diesel-electric vehicle or like drive, electrical apparatus governing the transmission of power from generator to motor is actuated by a driver-operated control through a yielding connection which permits, in event of the prime mover being overloaded, this control to be overridden by another operated by an enginedriven governor near the end of its travel. As shown in Fig. 1, a carbon pile 8 in the generator field controls the power transmitted to the motor, the degree of compression of the pile being controlled by a fluid-pressure doubleacting servomotor 9, 10, the valve 14 of which is operated by a link 19 moved by a cam 4 on the driver-operated control shaft 2. A yielding spring-connection 24 obtains between the valve stem and link when the link moves the valve in a direction to increase pressure on the pile, so that under overload conditions the valve may be moved in the opposite direction to relieve the load by a rod 15 which is pivoted at 16 and moved by an engine-driven governor 5, 6. The end 17 of' the rod is normally clear of an extension 18 of the valve stem but engages the last and over-rides control by link 19 when the engine speed so falls that the governor 5, 6 is near the end of its travel. A cam 3 on the shaft 2 controls the spring-loading on the governor and, thus, the engine power output. The link 19 may be replaced by a rack-andpinion mechanism. The driver-operated control may act directly on the pile through a spring, in which case the servomotor, for relieving the spring pressure under overload conditions, may be single-acting. Specification 532,741 is referred to in the first Provisional Specification.

Title: Soluble and fusible copolymers which can be converted into infusible and insoluble resins
IPC: C08K5/12
Filed: 1955-08-10
Abstract: A soluble and fusible resin capable of being converted into an insoluble and infusible resin which does not support combustion comprises a copolymer containing 80 to 90 per cent of vinyl chloride and/or vinylidene chloride and 1 to 20 per cent of an allyl ester of acrylic, methacrylic or a -chloroacrylic acid.  The resin may be prepared by subjecting to polymerization conditions a mixture of vinyl chloride and/or vinylidene chloride with an allyl ester of acrylic, methacrylic, or a -chloroacrylic acid dissolved in appropriate proportions in a solvent, such as acetone, dioxane or carbon tetrachloride, which dissolves both the monomeric materials and the soluble and fusible resin obtained therefrom, and terminating the polymerization before gelation sets in, preferably by the addition of a non-solvent for the polymer,such as methanol.  The allyl ester is preferably introduced into the polymerization vessel as the polymerization proceeds, the rate of addition being so regulated that the ratio of the proportions of monomers is maintained constant. 2-azodi-isobutyronitrile may be used as catalyst.  The resin may be converted to the insoluble, infusible state by prolonged heating, or by heating in the presence of a polymerization catalyst such as tertiary butyl perbenzoate or benzoyl peroxide and/or another mono- or poly-functional monomer such as diallyl phthalate. Solutions of the soluble fusible polymers in acetone, carbon tetrachloride or dioxane may be used for impregnating fabrics or as lacquers.

IPC: G01N23/18
Filed: 1961-06-27
Abstract: 933,893. Welding by pressure. ROLLSROYCE Ltd. June 7, 1962 [June 27, 1961], No. 23314/61. Class 83 (4). The extent of a weld slug e.g. formed by resistance welding, is checked by forming one or more recesses, indentations or holes in one or both of the members to be welded prior to welding, and after welding using an X-ray test or equivalent or visual test to determine whether the recess, indentation or hole is partly or wholly removed or filled. In resistance lap welding tubes 10, 11, Fig. 1, a groove 12 of depth equal to the required depth of fusion is formed in one of the members 10. If during welding insufficient fusion occurs the groove 12 is not completely filled and this is revealed by X-ray inspection. Recesses 16, Fig. 4, formed in the edge of a member 15 to be resistance butt welded to a member 14 serve a similar purpose. In resistance lap welding bores 18, Fig. 6, are formed through one or both of the workpieces 10, 11. After welding the portion 20 of the bore 18 outside the weld slug 19 is filled with gas and molten metal. The depth of the portion 20 is revealed by X-ray or by use of a dye penetrant. In a modification, bores 21, Fig. 8, are formed to such a depth as to be filled with fused weld metal if a satisfactory weld is made or as shown to remain unfilled if the extent of the weld slug 22 is insufficient.
